JCWE is a tool that provides a versatile set of integrations with Confluence. And one way to keep things neat we made Global Confluence Admin since we are retrieving Jira application id from Confluence, and this needs an administration privilege in Confluence.
When you first install Confluence, you need to define a Global Confluence Admin which has an admin privilege on Confluence side.
Access JCWE administration
